看到保罗的博客上有一篇介绍让文字抖动的文章，心想可能以后会用的到，便再此做个记录。

以下是示例代码

<style>
/*文字摇摆*/
    @keyframes shake-it{
    0%{
        text-shadow: 0 0 rgba(0, 255, 255, .5), 0 0 rgba(255, 0, 0, .5);
    }
    25%{
        text-shadow: -2px 0 rgba(0, 255, 255, .5), 2px 0 rgba(255, 0, 0, .5);
    }
    50%{
        text-shadow: -5px 0 rgba(0, 255, 255, .5), 3px 0 rgba(255, 0, 0, .5);
    }
    100%{
        text-shadow: 3px 0 rgba(0, 255, 255, .5), 5px 0 rgba(255, 0, 0, .5);
    }
}
</style>

<button id=aaa>请点我吧！</button>

<script>
function paul_shake(action, selector) {
    var status = false;

    action.addEventListener("click", function () {
        if(status === true){
            status = false;
            selector.style = "";
        }
        else{
            status = true;
            selector.style = "animation: shake-it .5s reverse infinite cubic-bezier(0.68, -0.55, 0.27, 1.55)";
        }
    })
}
paul_shake(aaa, document.body);
</script>

第二种方法。
样式css

.douyin{
    animation: uk-text-shadow-glitch .65s cubic-bezier(1,-2.91,0,3.79) 0s infinite normal both running;
}
@keyframes uk-text-shadow-glitch {
    0% {
        text-shadow: none
    }
    25% {
        text-shadow: -2px -2px 0 #ff0048,2px 2px 0 #3234ff
    }
    50% {
        text-shadow: 2px -2px 0 #ff0048,-2px 2px 0 #3234ff
    }
    75% {
        text-shadow: -2px 2px 0 #ff0048,2px -2px 0 #3234ff
    }
    100% {
        text-shadow: 2px 2px 0 #ff0048,-2px -2px 0 #3234ff
    }
}
@keyframes uk-flicker {
    0% {
        opacity: 0
    }
    10% {
        opacity: .6;
        transform: scale(.8)
    }
    20% {
        opacity: 0
    }
    40% {
        opacity: 1
    }
    50% {
        opacity: .2;
        transform: scale(1.1)
    }
    100% {
        opacity: 1;
        transform: scale(1)
    }
}

cubic-bezier(1,-2.91,0,3.79) 是贝赛尔曲线，数值越大，抖的越厉害。
调用，加上类名就可以了。
